I have a Dell Optiplex A10 Plus 7420 running Windows 11 Pro. I want to dual boot with Windows XP. I have restored a backed up copy of Windows XP onto a D drive and have been unable to configure the boot loader to find the Windows XP partition. Furthermore I believe critical elements are missing such as Ntldr, Boot.ini etc... I downloaded multiple copies of the Windows XP Recovery EasyRE ISO and successfully installed a copy on a bootable 16GB USB stick formatted Fat32 using Easy USB Creator . Or so I thought but the USB won't boot. I've tried other USB creator tools such as ISO to USB and Rufus but to no avail. Can anyone suggest what I'm doing wrong?
